AC vs DC Battery Storage: What''s right for your home?

The biggest difference between them is in the distances they can travel without suffering major power losses. For example, AC can travel long distances without losing much power whereas DC electricity can''t travel so far but is much easier to store. Since AC is much better than DC for long-distance transmission, the power grid uses AC.

How Lithium-ion Batteries Work | Department of Energy

The movement of the lithium ions creates free electrons in the anode which creates a charge at the positive current collector. The electrical current then flows from the current collector through a device being powered (cell phone, computer, etc.) to the negative current collector. The separator blocks the flow of electrons inside the battery.
